With the DiRaSelect 300we
expand our product range of receiver accessories by an additional component. Via
USB up to three different receiving antennas from 9 kHz - 300 MHz can be switched
loss-free to one output socket.

High sensitivity and
excellent strong signal handling

With the DiRaWave 032 we introduce the third generation of PC-controlled shortwave
receivers from own development and production.

We have added an extra section concerning support
of the DRB 30
and DRB 32.

DRB 32-4 at the Arkala Extremes Project

This special model
consisting of 4 coherent DRB 32 receiver units for simultanious 4-channel reception
is used
for measurements of the possibly
highest 14MHz antenna in the world at Arkala/Northern Finland since July 2007.

These data are needed to create a mathematical
model for antenna simulation. Design goal is development of "intelligent antennas"
which deliver always the highest available signal-to-noise (SNR) ratio.

DRB 32 at the International Broadcasting Convention (IBC)
2007

Our new semiprofessional DiRaBox DRB 32 will
be showed up at the DRM - EBU Village Stand # 10-411 IBC 2007 from 07 - 11 September
2007 in Amsterdam/NL .

DRB 32 - New DiRaBox

With the new DRB 32
we introduce a modified concept especially for semiprofessional applications with
enhanced performance:

The test was made in Finland, DX
stations were Radio New Zealand & Wantok Radio Light in Papua New Guinea. Short
excerpt from the conclusion: "...
the small box is really capable to receive signals as good as more expensive models."

DRB 30 - Test report concerning DRM reception
with the new 2006 model

A new comprehensive DRM reception
test report is now available. Rainer Suckow who runs the DRM website section of
the Funktechnikmuseum Koenigs Wusterhausen ( birth place of broadcast in Germany
) has written a voluminous test report regarding the new DRB 30 model at many
different daily reception conditions.

DRB 30 - Single sample achieves max. 49.5dB
SNR DRM performance

After a AGC modification of the DRB
30 the DRM performance was measured in combination with the DREAM software. The
best sample achieved 49.5dB SNR, the other samples were in the range of 38 - 46dB

All units of the 2006 model series
already include this modification, elder units are upgradeable.

How to build a simple active antenna for the
DRB 30

Simple but efficient: Only four components
are necessary to construct this simple
active antenna suited for the DRB 30. The receiving range
is from AM to FM (0.5 - 100MHz) with good performance.
